Given that complaints about unsuitable advertisements on Transport for London (TfL) services can in fact generate additional publicity for the companies involved, will you consider carrying out a more comprehensive review of TfL advertising policies?

Transport for London (TfL) has a comprehensive and rigorous advertising policy and copy review process, and its media partners continue to work with advertisers to ensure that all advertising copy that runs on TfL’s network complies with TfL policy and Advertising Standard Authority (ASA) regulations. Where necessary, the advice of the Committee of Advertising Practice (CAP) may be sought to ensure that, in their view, the advertising copy complies with the advertising Code.
